Introduction to uc-locale-ja_JP-15.0.0.1-16.cop.sha512

This cryptographic checksum file validates the integrity of Cisco’s Japanese (ja_JP) localization package for Unified Communications Manager (CUCM) 15.0.0 deployments. Designed for enterprises operating in Japan, the COP file enables full-width character support and cultural compliance across administrative interfaces, IP phone displays, and Webex Room devices.

Released under Cisco’s Q3 2025 software maintenance cycle, this package aligns with Japan’s Act on the Protection of Personal Information (APPI) requirements. It supports CUCM 15.0.0 installations and backward compatibility for Webex Room Series devices manufactured post-Q2 2024, ensuring seamless integration with Japan-specific telephony standards.
